IMPORTANT SAFETY INSTRUCTIONS

WARNING

Do not attempt to operate this tool until you have read all of the instructions, safety information, etc.

contained in this manual thoroughly and understand them completely. Failure to comply may result

in accidents involving re, electric shock, or serious personal injury.

• Do not start cutting until you have a clear work area, secure footing, and a planned retreat

path from the falling tree. Cluttered areas invite accidents.

• Keep all children, bystanders, visitors, and animals out of the work area while starting or

cutting with the chainsaw.

• Do not operate chainsaw in an explosive atmosphere, such as in the presence of ammable

liquids, gases, or dust. Power tools create sparks that may ignite the dust or fumes.

WARNING

Use outdoor extension cords marked SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJTW-A, or

SJTOW-A. These cords are rated for outdoor use, and reduce the risk of electric shock.

• Polarized Plugs. To reduce the risk of electric shock, this tool has a polarized plug (one blade

is wider than the other). This plug will only t into a polarized outlet one way. If the plug does

not t fully into the outlet, reverse the plug. If it still does not t, contact a qualied electrician

to install the proper outlet. Do not change the plug in any way.

• Make sure your extension cord is in good condition. When using an extension cord, be sure

to use one heavy enough to carry the current your product will draw. A wire gauge size

(A.W.G.) of at least 14 is recommended for an extension cord 50' (15 m) or less in length. A

cord exceeding 100' (30 m) is not recommended. If in doubt, use the next heavier gauge. The

smaller the gauge number, the heavier the cord. An undersized cord will cause a drop in line

voltage, resulting in loss of power and overheating.

• Inspect extension cords periodically, and if damaged, have repaired by a licensed electrician.

Constantly stay aware of cord location. Following this rule will reduce the risk of electric shock

or re.

• Wear snug tting clothing. Always wear heavy, long pants, overalls, jeans or chaps made of

cut-resistant material or ones that contain cut-resistant inserts. Wear non-slip safety footwear.

Wear non-slip heavy duty gloves to improve your grip and to protect your hands. Do not wear

jewelry, short pants, sandals, or go barefoot. Do not wear loose-tting clothing that could be

drawn into the motor or catch the chain or underbrush. Secure hair so it is above shoulder

level.

• Heavy protective clothing may increase operator fatigue, which could lead to heat stroke.

• During weather that is hot and humid, heavy work should be scheduled for early morning or

late afternoon hours, when temperatures are cooler.

• Wear eye protection that is marked to comply with ANSI Z87.1 as well as hearing and head

protection when operating this equipment. Hearing protection should be worn.

• Always be aware of what you are doing when using the chainsaw. Use common sense. Do

not operate the chainsaw when you are tired, ill, or under the inuence of alcohol, drugs, or

medication.

IMPORTANT SAFETY INSTRUCTIONS

• Do not expose the chainsaw to rain.

• Do not use the chainsaw in damp or wet locations.

• Stay alert and pay attention to what you are doing.

• Keep all parts of your body away from the saw chain when the unit is running.

• Always carry the chainsaw by the front handle with the power cord removed and the guide bar

and saw chain positioned to the rear.

• Never let anyone use your chainsaw who has not received adequate instructions in its proper

use. This applies to rentals as well as privately owned saws.

• Before you start the unit, make sure the saw chain is not contacting any object.

• Stop the chain saw before setting it down.

• To avoid accidental starting, never carry the unit with your nger on the trigger switch .

• Maintain the unit with care. Keep the cutting edge sharp and clean for best performance and

to reduce the risk of injury. Follow instructions for lubricating and changing accessories.

• Keep handles dry, clean, and free of oil and grease.

• Do not operate a chainsaw with one hand! Use a rm grip with thumbs and ngers encircling

the chainsaw handles. Serious injury to the operator, helpers, bystanders, or any combination

of these persons may result from one-handed operation. A chainsaw is intended for two-

handed use.

• Avoid body contact with grounded surfaces such as metal pipes and wire fences. There is an

increased risk of electric shock if your body is grounded.

• Do not operate a chainsaw that is damaged, improperly adjusted, or not completely and

securely assembled. Chain should slow to a stop when the trigger switch is released. If the

chain continues to turn after the trigger switch has been released, have the unit serviced by

your nearest GreenWorks™ service dealer.

• Check for damaged parts, misalignment or binding of moving parts, broken parts and

mountings, and any other condition that may affect the operation of the tool.

• All chainsaw service, other than the items listed in the operation and maintenance sections,

should be performed by your nearest GreenWorks™ service dealer.

• Always maintain a proper stance.

• Do not use chainsaw if switch does not turn it on and off. Have defective switch replaced by

authorized service centre.

• Do not adapt your chainsaw to a bow guide or use it to power any attachments or devices not

listed for the saw.

• Disconnect chainsaw from power supply when not in use, before servicing, and when making

adjustments and changing attachments, such as saw chain and bar.

• Do not cut vines and/or small underbrush.

• Do not operate a chainsaw in a tree, on a ladder, or on scaffolding. Doing so is extremely

dangerous.

NOTE: The size of the work area depends on the job being performed as well as the size of the tree or

workpiece involved. For example, felling a tree requires a larger work area than making bucking cuts.

IMPORTANT SAFETY INSTRUCTIONS

• Use extreme caution when cutting small brush and saplings, because small material may

catch the saw chain and be whipped toward you or pull you off balance.

• When cutting a limb that is under tension, be alert for spring back, so that you will not be

struck when the tension in the wood bers is released.

• Do not force the chainsaw. The job can be performed better if the saw is used at the rate that

it was designed to work at.

• Always use the right product for your application. The chainsaw should be used for cutting

wood only. Never use the chainsaw to cut plastic, masonry or non-wooden building materials.

• Do not use the chainsaw for purposes other than what it is intended for.

• Store chainsaw when not in use. Chainsaw should be stored in a dry and high or locked area,

out of the reach of children.

•Save these instructions. Refer to them frequently, and use them to instruct others who may

use this tool. If you loan someone this tool, also loan them these instructions.

WARNING(Proposition 65)

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities

contains chemicals known to cause cancer, birth defects or other reproductive harm. Some

examples of these chemicals are:

• lead from lead-based paints

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically treated lumber.

Your risk of exposure to these chemicals varies depending on how often you do this type of

work. To reduce your exposure to these chemicals, work in a well-ventilated area, and work with

approved safety equipment, such as dust masks that are specially designed to lter out microscopic

particles.

SAVE THESE INSTRUCTIONS

GENERAL SAFETY RULES

WARNING

Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the

guide bar, or when the wood closes in and pinches the saw chain in the cut. Contact at the upper

portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for

an instant. The result is a lightning fast reverse reaction that kicks the guide bar up and back toward

the operator. If the saw chain is pinched along the top of the guide bar, the guide bar can be driven

rapidly back toward the operator. Either of these reactions can cause loss of saw control, which

can result in serious injury. Do not rely exclusively on the safety devices built into the saw. As a

chainsaw user, you should take several steps to keep your cutting jobs free from accident or injury.

THE FOLLOWING PRECAUTIONS SHOULD BE FOLLOWED TO MINIMIZE

KICKBACK:

1. Always grip the saw rmly with both hands. Hold the saw rmly with both hands when the

unit is running. Place your right hand on the rear handle and your left hand on the front

handle, with your thumbs and ngers encircling the chain saw handles. A rm grip and a

stiff left arm will help you maintain control of the saw if kickback occurs.

2. Make sure that the area in which you are cutting is free of obstructions. Do not let the

nose of the guide bar contact a log, branch, fence, or any other obstruction that could be

hit while you are operating the saw.

3. Always cut with the unit running. Fully squeeze the trigger switch and maintain cutting

speed.

4. Use only the replacement guide bars and low-kickback chains specied by the

manufacturer for the saw.

• With a basic understanding of kickback, you can reduce or eliminate the element of surprise.

Sudden surprise contributes to accidents.

• Keep proper footing and balance at all times.

• Do not cut above shoulder height or overreach when cutting.

• Follow the sharpening and maintenance instructions for the saw chain.

SYMBOLS

ELECTRICAL

DOUBLE INSULATION

Double insulation is a concept in safety in electric power tools, which eliminates the need for the

usual three-wire g rounded power cord. All exposed m etal parts a re isolated from the i nternal

metal motor components w ith protecting i nsulation. Double insulated tools do not need to be

grounded.

NOTE: Servicing of a product with double insulation requires extreme care and knowledge of the system and

to your nearest authorized service center for repair. Always use original factory replacement parts when

servicing.

WARNIN G

The double insulated system is intended to protect the user from shock resulting from a break in

the tool’s internal insulation. Observe all normal safety precautions to avoid electrical shock.

ELECTRICAL CONNECTION

This product has a precision-built electric motor. It should be connected to a power supply that is

120V, AC only (normal household current), 60 Hz. Do not operate this product on direct current

(DC). A substantial voltage drop will cause a l oss of power and t he m otor will overheat. I f the

product does not operate when plugged into an outlet, double-check the power supply.

EXTENSION CORDS (See Figure 4)

When using a power t ool a t a considerable distance from a power source, be sure to use an

extension cord that has the capacity to handle the current the product will draw. An undersized

cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to

determine the minimum wire size required in an extension cord. Only round jacketed cords listed

by Underwriter’s Laboratories (UL) should be used.

When working outdoors with a product, use an extension cord that is designed for outside use.

This type of cord is designated with “W-A” or “W” on the cord’s jacket.

Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.

A proper extension cord is available at an authorized service center.

It is possible to tie the extension cord and power cord in a knot to prevent them from becoming

power cord into the receptacle end o f the extension cord. This method can also be u sed to tie

two extension cords together.

Fig. 4

ELECTRICAL

WARNING

Keep the extension cord clear of the working area. Position the cord so that it will not get caught

on lumber, tools, or other obstructions while you are working with a power tool. Failure to do so

can result in serious personal injury.

WARNING

Check extension cords before each use. If damaged replace immediately. Never use the product

with a damaged cord since touching the damaged area could cause electrical shock resulting in

serious injury.

ADDING BAR AND CHAIN LUBRICANT (See Fig. 6)

Use a lubricant that is designed for chains and chain oilers, and is formulated to perform over a

wide temperature range with no dilution required.

NOTE: The chainsaw comes from the factory with no bar and chain oil added. Level should also be

checked after every 20 minutes of use, and relled as needed.

• Remove oil cap.

• Carefully pour the bar and chain oil into the tank.

• Wipe off excess oil.

• Check and ll the oil tank when quick-view oil indicator is below the MIN. line.

• Repeat as needed.

NOTE: Do not use dirty, used or otherwise contaminated oils. Damage may occur to the bar or chain.

NOTE: It is normal for oil to seep from the saw when not in use. To prevent seepage, empty the oil tank

after each use, then run for one minute. When storing the unit for a long period of time (three months or

longer), be sure the chain is lightly lubricated. This will prevent rust on the chain and bar sprocket.

PREPARING FOR CUTTING

PROPER GRIP ON HANDLES (See Fig. 9)

See General Safety Rules for appropriate safety equipment.

• Wear non-slip gloves for maximum grip and protection.

• Hold the saw rmly with both hands. Always keep your left hand on the front handle and

your right hand on the rear handle so that your body is to the left of the chain line.

• Maintain a proper grip on the saw whenever the motor is running. The ngers should

encircle the handle, with the thumb wrapped under the handlebar. This grip is least likely

to be broken by a kickback or other sudden reaction of the saw. Any grip in which the

thumb and ngers are on the same side of the handle is dangerous, because a slight kick

of the saw can cause loss of control.

WARNING

Never use a left-handed (cross-handed) grip or any stance that would place your body or arm

across the chain line.

WARNING

DO NOT operate the switch trigger with your left hand and hold the

front handle with your right hand. Never allow any part of your body

to be in the chain line while operating a saw.

PROPER CUTTING STANCE (See Fig. 10)

• Balance your weight with both feet on solid ground.

• Keep left arm with elbow locked in a “straight arm” position to withstand any kickback force.

• Keep your body to the left of the chain line.

• Keep your thumb on underside of handlebar.

BASIC OPERATING/CUTTING PROCEDURES

Practice cutting a few small logs using the following technique to get the “feel” of using the saw

before you begin a major sawing operation.

• Take the proper stance in front of the wood.

• Press the switch lock and squeeze the switch trigger, then release switch lock and let the

chain accelerate to full speed before entering the cut.

• Begin cutting with the saw against the log.

• Keep the unit running the entire time you are cutting, maintain a steady speed.

• Allow the chain to cut for you; exert only light downward pressure. Forcing the cut could

result in damage to the bar, chain, or motor.

• Release the trigger switch as soon as the cut is completed, allowing the chain to stop. If you

run the saw without a cutting load, unnecessary wear can occur to the chain, bar, and unit.

• Do not put pressure on the saw at the end of the cut.

WORK AREA PRECAUTIONS (See Fig. 11)

• Cut only wood or materials made from wood; no sheet metal, no plastics, no masonry, no non-

wooden building materials.

• Never allow children to operate the saw. Allow no person to use this chainsaw who has not

read this Owner's Manual or received adequate instructions for the safe and proper use of this

chainsaw.

• Keep everyone – helpers, bystanders, children, and animals – at SAFE DISTANCE from the

cutting area. During felling operations, the safe distance should be a least twice the height of

the largest trees in the felling area. During bucking operations, keep a minimum distance of

15' (4.6 m) between workers.

• Always cut with both feet on solid ground to prevent being pulled off balance.

• Do not cut above chest height, because a saw held higher is difcult to control against

kickback forces.

• Do not fell trees near electrical wires or buildings. Leave this operation for professionals.

• Cut only when visibility and light are adequate for you to see clearly.
